Hi! I am a Member of Technical Staff at xAI reasoning, working on agentic RL to improve grok factuality and usefulness. I was previously Senior Research Scientist at Bytedance Seed Team, working on code LLMs and Agents. I got my MS in CS from UIUC and decided to move into industry rather than PhD. Before that, I obtained my bachelor degree in Zhejiang University.

My current research work includes:

• LLM Factuality, RL, synthetic data
• LLM in coding and math [1] [2]

Previously in academia, I worked on:

• LLM Trustworthy [3] [4] and Evaluation [5] [6]
